Re: [問題] ServerSocket.accept() 要怎麼強制結束?

試一下 ServerSocket 的 setSoTimeout()：
setSoTimeout
public void setSoTimeout(int timeout)
throws SocketException
Enable/disable SO_TIMEOUT with the specified timeout, in milliseconds.
With this option set to a non-zero timeout, a call to accept() for this
ServerSocket will block for only this amount of time. If the timeout expires,
a java.net. SocketTimeoutException is raised, though the ServerSocket is
still valid. The option must be enabled prior to entering the blocking
operation to have effect. The timeout must be > 0. A timeout of zero is
interpreted as an infinite timeout.
Parameters:
timeout - the specified timeout, in milliseconds
Throws:
SocketException - if there is an error in the underlying protocol,
such as a TCP error.
Since:
JDK1.1
